mtd: add get/set of_node/flash_node helpers
Linux commit 28b8b26b308 ("mtd: add get/set of_node/flash_node helpers")
We are going to begin using the mtd->dev.of_node field for MTD device
nodes, so let's add helpers for it. Also, we'll be making some
conversions on spi_nor (and nand_chip eventually) too, so get that ready
with their own helpers.

[Philippe Reynes: only add function nand_set_flash_node and
nand_get_flash_node because others were already backported]
